About this map

Arock stands as a small ranching hub in Malheur County, situated along the Old Ion Hwy where the landscape transitions into the high desert plains. This modern survey illustrates a sophisticated network of water management essential for the arid environment, featuring the North Side Canal and South Side Canal which divert resources toward various impoundments. The terrain is marked by distinctive local landmarks such as Hidden Valley and Merrill Springs Rim, reflecting a geography shaped by both volcanic basalt and seasonal water flow.

Local history and genealogy researchers will find the location of the Arock Cem north of the main settlement, providing a point of reference for families tied to the early 20th-century homesteading era. The map details numerous smaller reservoirs, including No Catchum Reservoir and Lynde Reservoir, which support the livestock operations that have long defined this corner of Oregon. Named routes like Bogus Ranch Rd and Lava Beds Rd further trace the human imprint on this expansive landscape.
